You would have to find out how many square feet the lawn is first:
70 x 50 = 3500 square feet
You are told that one pound = 200 square feet so use this to calculate how many pound you’ll need for 3500 square feet.
3500 square feet divided by 200 square feet = 17.5 pounds
Answer: 17.5 pounds
4 and 1/6 is the mixed number, or 4 and 2/12
2 units, 3 units, 6 units
36 units, 1 unit, 1 unit
9 units, 2 units, 2 units
12 units, 3 units, 1 unit
All options stated above would result in a volume of 36 cubic units.
You would round 1506 to 1500 and and do not round 2. So then you woulddo 1500 divided by 2 to get 750!
